Success Stories

Conveying beet pulp straight from the lagoon

Beets, particularly sugar beets and specially-bred energy beets, are becoming more and more popular. The storage of the beets in silos or silage tubes is complicated and expensive. Collecting beet pulp in foil-lined reservoirs represents a comparatively simple and cost-effective alternative to this. More

Low-wear conveyance of industrial waste water:
Robust rotary lobe pumps make water treatment easier

Used service water from industrial processes is one of the most problematic types of waste water due to its composition, which is often very demanding for conveying systems. In order to enable problem-free treatment of this kind of waste water in spite of this, the T.Envi® is specially designed for a long service life with minimum wear, so that it can also convey extremely abrasive media without any problem.

Robust grinder prevents shutdown of system due to coarse material in the biomass or sludge

In order to be economically viable, biogas plants today must be able to be operated using a variety of energy crops and bio waste. However, changing sources can rapidly become a problem for the operating company: The consistency and composition of the biomass is difficult to predict due to natural fluctuations in their origin, coarse material continues to block lines and pumps.

A new generation of rotary lobe pumps performs bilge pumping and conveying tasks maintenance-free and in extremely limited space

wo things are severely limited on ships: space and time. Compactness is particularly vital in the machine room, as each centimetre means a loss at the expense of valuable transport capacity. At the same time, the systems have to be robust, as manpower can hardly be switched to repairs at sea and interim port stops are to be avoided at all costs for reasons of time. So maximum demands are placed on safety-critical systems such as bilge pumps. More

aBP- bridge breaker prevent the constructions stop

There are two aspects of wastewater treatment plants at Celle (Germany) which have a direct use: in addition to cleaning waste water, the sewage sludge which arises with the nutrients it contains can be used later as manure in agriculture. The sewage sludge is transported via a pressure pipe around 25 metres in length with several right-angled turns – ten metres of it being geodesic – to a silo and from there it is later spread over agricultural areas. So that the mix can be stored, it is first dewatered in an angle press and flocculating agents are added. More

Pump technology for maritime applications:

Universally deployable displacement pumps ensure reliable, smooth conveyance of a very wide range of media

When pumps are used on ships and in ports, the technology must meet special requirements: this means the pumps should not only cope with a really wide variety of fluids, such as wastewater and lubricant oil, but should also be as space-saving, maintenance-free and easy to handle as possible.

Brazilian hydroelectric power stations rely on pump know-how from Germany

While Germany still faces many unsolved problems in terms of implementing the energy turnaround, they have moved significantly further on in South America. Of all the countries, the developing nation of Brazil is proving itself to be the role model when it comes to renewable energies. Around 75 percent of the electricity requirement is covered by hydroelectric power there. More

Reliable sludge removal for water jet cutting:
Robust rotary lobe pump will even pump highly abrasive residual water without any damage

Cutting systems, which are based on high-pressure water jets and do not alter the material structure through their energy input like lasers do, are establishing themselves in more and more areas, such as robotics or automotive manufacturing. A cutting aid, an abrasive, is mixed into the water to increase cutting performance. This abrasive is frequently a fine garnet sand. After the cutting process, the water-sand mixture has to be separated again, so that the sand can be disposed of. A manufacturer of water jet cutting systems offers an automated solution for its systems to remove and separate the sludge from the water. More...


Products

NEMO® Pump BY

NEMO® BY Progressing Cavity Pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed.

NEMO® BO/BS Pump with Hopper in Block Construction and Flanged Drive

The NEMO® BO/BS Progressing Cavity Pump with square/rectangular hopper and coupling rod with feeding screw and force-feed chamber is employed in almost all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance.

The NETZSCH TORNADO® Mobile

A TORNADO® rotary lobe pump fastened onto a mobile base – this is the NETZSCH TORNADO® Mobile. The concept of mounting the equipment onto a car or truck trailer makes it possible to pump large quantities of fluids with solid content, wastewater and slurries at the most unusual of sites.

NEMO® SY Industrial Construction in Bearing Block Design with Free Shaft Extension

The NEMO® SY Progressing Cavity Pump is used for demanding applications in every branch of industry around the globe. In bearing block design with free shaft extension, this pump can be run with any type of drive, such as servo motors, diesel motors or hydraulic drives.

NEMO® B.Max® Mixing Pump

The NEMO® B.Max® is setting new standards with its maximum mixing and conveying capabilities for biosubstrates.

M-Ovas® Grinding System

NETZSCH M-Ovas® grinding systems can be used wherever it is essential that solid matter in fluids be broken down reliably to ensure the prevention of pipe clogging and damage to downstream equipment.

NEMO® BP Hopper Pump with Feeding Screw and Bridge Breaking Paddle or aBP-Module

For highly viscous, compacted and crumbly substances that have a tendency to bridge, the NEMO® BP Progressing Cavity Pump is the optimal solution. The NEMO® BP can be used in nearly all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance with dosing in proportion to rotation speed.

NEMO® BF Progressing Cavity Pump with Hopper and Feeding Screw

The NEMO® BF is used in all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance with dosing in proportion to rotation speed. It is employed primarily for highly viscous, compacted and crumbly substances that do not have a tendency to bridge.

Taskmaster®

For applications with particularly large solid objects in the wastewater flow, the Taskmaster® is your ideal partner. Various tooth and spacer width plate combinations are available for different degrees of grinding.

NEMO® C.Pro®

The NEMO® N-Ipos CY C.Pro® Dosing Pump is a fully synthetic pump for the precise dosing of a great variety of chemicals in environmental technology and the chemical industry. Its synthetic construction makes it perfectly suited for the gentle and low-pulsation conveyance and dosing of aggressive or non-aggressive chemicals.

TORNADO® Rotary Lobe Pump

The TORNADO® rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.
